@abr:
Check out the post in the Scripting Forum: DO11: Script to open/close related folder tabs automatically
It's rudimentary at this point as we're still unable to do certain things that would make it a bit smoother to use like be able to re-use existing tabs (NEWTAB=findexisting) as well as be more selective in closing the linked tab (like holding a qualifier key down). I'll be posting some feature requests to GPSoft later to see if some of this can be expanded upon.
At the moment, if the script is installed, it's active. I think you mentioned being able to disable it. I'll have a look at that after you give some initial feedback...
